Jockey via eBay offers the Coopers by Jockey Men's Woven Boxer Shorts in seven colors for $4.99 with free shipping. That's tied with our mention from last week and the lowest total price we could find by $2. They're available in sizes from S to XL, although not in all size/color combinations.
Note that while the white color is pictured, it is not offered.
